Hi,
just read the manual for the KAT100. It states to
remove C44 on K2 control board before using KAT100.
OK. How does this affect the use of the K2 without the
KAT100, with KAT2?
You see, I want to switch covers from qrp to qro :-)
Thanks
Gerhard
I am almost ready to start winding toroids for my K2. I have run into this
question before but never found an answer.
Suppose I wind a toroid, then check its inductance afterwards. I find that the
value is not exactly the same value as the schematic calls for, but after
removing one turn (or

C44 is explained in the following alert from Elecraft:
Gerhard,
Control Board C44 is not used on the newer K2s (it was only used on SN 3000
thru 3077 and may have been added to some lower serial numbered K2s). It
should be removed if C44 is present on your K2. See Elecraft Builder Alert
#19.
All will be fine with your QRP tuner.

Don
Mike,
Wind the toroids as specified - the K2 will work great with the specified
number of turns, and there are over 4000 of them already built to confirm
that statement.
Be certain to count each turn that passes through the center of the core.
If only the turns on the outside are counted,
Hello Mike,
a) use the # of turns in the assembly instructions, ...
Yes, like more than 4500 other K2 builder too!
b) change the number of turns, ...
No.

I have been getting reports on 80m that my SSB signal had some edge to it.
At first I put it down to RF feedback, but that was not the problem.

I will be heading out the door today around 1500 utc and should be at

I have the Autek antenna analyzer and think it's a good deal for the price.
A couple guys in our club have the MFJ analyzers, so I've had a chance to
compare. The MFJ display has more information on it, so it's easier to use.
I like the analog meter on the MFJ; it lets you more quickly find an

I have been in contact with Gary intermittantly since first coming across

i just bought some USB to serial port converters... like the one I have
been using for the piles of serial stuff i have. I have no connection to

serials from a USB port.
And they are very configurable... from the edgeport
I just finished the KX1 that I got from Santa. Everything seems to work
fine except my WM-2 is only seeing about 1.5 watts into a 50 ohm dummy load
on both 20 and 40 meters. What are the rest of you seeing?

Bob,
A Soldapullt PT209 desoldering pump can be got from Farnell for less than 10
pounds. The heat comes from your regular soldering iron, and the suck from
the pump. I have had one in use for 25 years and have never found the need
for anything more fancy. You might care to try one out before
I agree with this. When running you don't fiddle with too much.
What I would really, really, really like is true QSK for my K2. If I had

and RF signal line internally. Then I would use a software program to

Ok, I found the problem of no 30m band. It was what I suspisioned with the
18.100MHz crystal not oscillating and all the others were. I installed
another 18.100 crystal and BINGO the mojo started working. Tuned up
beautiful. I don't know what happened, or why the crystal would not
oscillate. I

I made that exact same mistake!!! When it came time to install R10, however,
I realized the through-hole should not be occupied, and I discovered my
mistake.
I have not gotten so far along as to test my SSB adapter yet, and I am glad
I found this before I got that far.
It's strange that we both
I want to say the combination of doing the 2.4 Khz cap mod, and
replacing the crystals on the RF board and SSB adapter( my ssb adapter
board was one of the very first ones to come out)and receiving a MD2

I can attest that this is also a problem with the Autek. I was using my
Autek analyzer to tune an antenna at a multi-op contest station that our
club was setting up. As I was tuning the antenna, every once in a while, the
readings would just go crazy. I started thinking that my meter was beginning

Leigh,
As preliminary filter alignment for SSB FL1, I recommend setting 2 markers
in Spectrogram - one at 300 Hz and the other at {filter bandwidth + 300
Hz}(- for 2.3 kHz filter use 300 and 2600 Hz). Then adjust the BFO to
center the passband between those markers.
That will produce a
